in reply to ImageMagick Point Query

Just a quick usage note: in Perl there is almost always an easier solution than C-style for loops

for my $col (50..99) 
{
    for my $row (150..199) 
    {
        #same code here
    }
}

It's a small point, but in my experience incorrectly handled iterator variables are a common source of mistakes. Letting Perl take care of that means fewer headaches.
